Lucien Bély, Bertrand Haan and Stéphane Jettot (Paris-Sorbonne) published an edited volume on the Peace of the Pyrenees (5 CTS 325).

English abstract:

The Franco-Spanish reconciliation concluded in
1659 was a key moment for Europe. Its long negotiation, its
celebration, and the memory of it nourished huge collective hopes, but
also a reflection on diplomatic, political, and financial balance,
evaluated through the prism of reason.
